In version 1012 and prior of Insteon's Insteon Hub, the radio transmissions used for communication between the hub and connected devices are not encrypted.

Wokka Lokka Q50 devices through 2021-11-30 allow remote attackers (who know the SIM phone number and password) to listen to a device's surroundings via a callback in an SMS command, as demonstrated by the 123456 and 523681 default passwords.

ISaGRAF Workbench communicates with Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x using TCP/IP. This communication protocol provides various file system operations, as well as the uploading of applications. Data is transferred over this protocol unencrypted, which could allow a remote unauthenticated attacker to upload, read, and delete files.

IBM Integration Bus 9.0 and 10.0 transmits user credentials in plain in clear text which can be read by an attacker using man in the middle techniques. IBM X-Force ID: 134165.

The update process of the Circle Parental Control Service on various NETGEAR routers allows remote attackers to achieve remote code execution as root via a MitM attack. While the parental controls themselves are not enabled by default on the routers, the Circle update daemon, circled, is enabled by default. This daemon connects to Circle and NETGEAR to obtain version information and updates to the circled daemon and its filtering database. However, database updates from NETGEAR are unsigned and downloaded via cleartext HTTP. As such, an attacker with the ability to perform a MitM attack on the device can respond to circled update requests with a crafted, compressed database file, the extraction of which gives the attacker the ability to overwrite executable files with attacker-controlled code. This affects R6400v2 1.0.4.106, R6700 1.0.2.16, R6700v3 1.0.4.106, R6900 1.0.2.16, R6900P 1.3.2.134, R7000 1.0.11.123, R7000P 1.3.2.134, R7850 1.0.5.68, R7900 1.0.4.38, R8000 1.0.4.68, and RS400 1.5.0.68.

An issue was discovered on Dahua DHI-HCVR7216A-S3 3.210.0001.10 build 2016-06-06 devices. The Dahua DVR Protocol, which operates on TCP Port 37777, is an unencrypted, binary protocol. Performing a Man-in-the-Middle attack allows both sniffing and injections of packets, which allows creation of fully privileged new users, in addition to capture of sensitive information.

The auto-update feature of Open Embedded Linux Entertainment Center (OpenELEC) 6.0.3, 7.0.1, and 8.0.4 uses neither encrypted connections nor signed updates. A man-in-the-middle attacker could manipulate the update packages to gain root access remotely.

A cleartext transmission of sensitive information vulnerability in Fortinet FortiManager 5.2.0 through 5.2.7, 5.4.0 and 5.4.1 may allow an unauthenticated attacker in a man in the middle position to retrieve the admin password via intercepting REST API JSON responses.

Using ktlint to download and execute custom rulesets can result in arbitrary code execution as the served jars can be compromised by a MITM. This attack is exploitable via Man in the Middle of the HTTP connection to the artifact servers. This vulnerability appears to have been fixed in 0.30.0 and later; after commit 5e547b287d6c260d328a2cb658dbe6b7a7ff2261.

arrow-kt Arrow before 0.9.0 resolved Gradle build artifacts (for compiling and building the published JARs) over HTTP instead of HTTPS. Any of these dependent artifacts could have been maliciously compromised by an MITM attack.

OpenAPI Tools OpenAPI Generator before 4.0.0-20190419.052012-560 uses http:// URLs in various build.gradle, build.gradle.mustache, and build.sbt files, which may have caused insecurely resolved dependencies.

An authentication flaw in Shenzhen Yunni Technology iLnkP2P allows remote attackers to actively intercept user-to-device traffic in cleartext, including video streams and device credentials.

JetBrains Ktor framework (created using the Kotlin IDE template) versions before 1.1.0 were resolving artifacts using an http connection during the build process, potentially allowing an MITM attack. This issue was fixed in Kotlin plugin version 1.3.30.

In /usr/local/etc/config/addons/mh/loopupd.sh on eQ-3 AG HomeMatic CCU2 2.29.22 devices, software update packages are downloaded via the HTTP protocol, which does not provide any cryptographic protection of the downloaded contents. An attacker with a privileged network position (which could be obtained via DNS spoofing of www.meine-homematic.de or other approaches) can exploit this issue in order to provide arbitrary malicious firmware updates to the CCU2. This can result in a full system compromise.

An issue was discovered in Flexense DiskBoss 8.8.16 and earlier. Due to the usage of plaintext information from the handshake as input for the encryption key used for the encryption of the rest of the session, the server and client disclose sensitive information, such as the authentication credentials, to any man-in-the-middle (MiTM) listener.
